To all whom may concern:

Be it known that I, \VI UAM O. Gmnhur, a citizen ofithe United States, res-id'm at Qm'aha, in thecounty of Douglas and tube ofillebrflsku, have invented new nild useful Improuements'in Shock-Absorbers, of which the following is a specification.

The present inventionfreletes to shock a] sorbers wh1ch are new commonl used 111 oouuectlon with uut0xnbb1les,.un the purpose ofw'hioh is to eliminate the sudden rebound gand resultant discomfort to passengers) o a flexed spring by retarding the action of the ring, so that its returminsteed of being sm l den, willbe gradual und shock to the bod of the vehicle and the occupants thereof will be prevent In the improvement which Ihave developed, and which will be hereinafter de scribed; the construction is such that there is uointerferencewlth the flexing of the a ring under its loud, it being free to yield ownis such that 'thieretardation will be effective wurdly without any appreciable retardation, so that its full resiliency under the loud 1s utilized, but the spring on its upwer'clmovemen". will be retarded; audthe improvement upon the sllgl testflexing and returnjof the sprin although the device, which I shall now eseribe in iietelil having reference to thedrmviugs which accompany end form a part of this disclosure, will be equally elfee tive in. retarding the return of the spring flOUliil Q. limit of.- its flexed position. ,In

other words, the action of the shoelgebsorber is only during that period when retnrclation is desirable, and is effective fromfthe mininuun degree of fiexure of the spring'to the mmtlmurn movement thereof.
